ACETYLENE- GAS LAMP.

Specification of Letters Patent.

Patented Get. 31, 19.11.

Application tiled December 3 1, 1910. Serial No. 600,345.

My invention relates to certain new' andv useful improvements inacetylene lamps, and the object ofamy invention is to so improve theconstruction as to cause the same to burn longer and steadier than hasheretofore been possible on a given charge of calcium cai'- bid, andalso to greatly decrease vthe liability of the lamp becoming clogged.

With these and other objects in view my invention consists in certainconstructions, combinations andarrangements of parts, ythe preferredform of which will be first described in connection with the accompany`ing drawings, and. then the invention parin the appended claims. 4

Referring to the drawings wherein the same part is designated by thesame reference numeral wherever it occurs., Figure 1 is a centrallongitudinal section of an lacetylene lamp in which my improvementsareenibodied; Fig. 2 is a perspective view of my improvement detachedt'roni` the lamp, and Fig. 3 is a central cross section of Fig. 2. A n

,5 ,designatesLa receptacle for containing calcium carbid which, in thetoi-in of my invention shown, is provided with a screwthreaded neck t3surrounded by a rubber gasketI 7 adapted to screw into a cap 8, on whichis mounted the water reservoir 9, having" a filler opening 10 and awater controlling valve 11, zuhipted to control the flow of water fromtyie water reservoir to4 the carbid receptacle.

l2 is a pipe extending from the water reservoir into the carbidreceptacle and `through which the water passes to the bottom of thereceptaclel and 12 is a rod loosely extending through the valve 11 andpipe 12 by means of which the carbid may be agitated.

13 is the burner which extends 'out from the top of the cap 8, and theinner end of the burner pipe is covered by a block ot' by a cross wire'15.

or similar substance 14 held in place All these parts so far describedare of a general torni ot burner, and consequently torni no part of myinvention.

In the use of a lamp ofthe above-referred to type it has been foundthat'after a few days use the felt 14; covering the end of the burnertube would become wet and clogged,

thus preventing the flow' ot gas and render' ing the lamp inoperative.Furthermore the .particles of carbid will coat the felt and work inaround the inner end ofthe burner tube,' which increases the tendency ofthe tube to ,clog up; By my invention I obviate this dilticulty andcause a lamp of the character thus described to burn continuouslywithout clogging.

16 designates a metal plate provided with a centralperforation 17,through which lthe water pipel l2 extends. .The plate is also providedwith the perforation's 18.

19 designates a section of cork secured to the under side of tlieplate16,' said cork bey ing provided with the central perforation 20 in linewith the perforation 17 of the plate, and the perforations 21 in linewith the pert'orations 18. Preferably and as` shown the pci'oi'ations'21are conical and provided with a bushing 21 wliichvinay be eitherintegral with the plate 16, as shown in Fig. 1., or 'separate therefrom,as shown in Fig. 3, and in the perforations 21 I place ainass of cotton,or the like 22, so that gas passing up to the burner must pass througl:the mass ot cotton. The cork fits snugly int-o the mouth ot' the carbid.receptacle and closes the same, lt prevents dampness passing up to the'.t'elt and consequently the felt cannot become clogged. Should thesmall i'nasses of cotton in the openings 21 become clogged they'can beeasily 'and quickly removed and'replaced. It is found'in practice,howevei', thatthese small masses of cotton do not clog up the way theblock of felt infront of the gas tube does when a lamp is not providedwith my invent-ion.

I realize that .considerable variation/is possible in the details ofconstruction and arrangement of parts Without departing from the .spiritof my invention, ,and I therefore do vnot intend to limit myself to thespecific form' shown and described.

. Having thus described my invention lamp which comprises a csmhdrsssrvo, a, csp for the reservoir, a Wssl' rscspmcle molmed on the csp,s bunrney @Xmuding fom the csp and a.
